   item       is the item for which a version string is to be 
              returned. item may be &quot;TOOLKIT&quot;, entry point names, 
              or program names. item is case insensitive. 
 
              Currently, the only item supported is &quot;toolkit&quot; 
              and it will return the toolkit version number. 
 
              Any other item will return &quot;No version found.&quot;

   Suppose you want to find out the recent Toolkit configuration 
   version number. Using the code fragment below: 
 
      ConstSpiceChar  * versn;

      versn = <b>tkvrsn_c</b> ( &quot;TOOLKIT&quot; ); 
 
   The pointer versn would refer to a string similar to the one 
   shown below (except that the version will be current): 
 
      &quot;CSPICE_N0035&quot;

   -CSPICE Version 2.3.0, 06-FEB-2002 (EDW) (NJB)  

      Changed the return type from (SpiceChar *) to (ConstSpiceChar *).
      Corrected example code to show use of (ConstSpiceChar *) return 
      type. Edited the header.

   -CSPICE Version 2.2.0, 03-SEP-1999 (NJB)  
   
      Return type changed to (SpiceChar *).  Function now cleans
      out version string before writing to it.
       
   -CSPICE Version 2.1.0, 08-FEB-1998 (NJB)  
   
      References to C2F_CreateStr_Sig were removed; code was
      cleaned up accordingly.  String checks are now done using
      the macro CHKFSTR_VAL.
       
   -CSPICE Version 2.0.0, 11-NOV-1997 (NJB)

      Updated to use the SPICELIB routine TKVRSN to obtain
      the version string for SPICELIB.  Updated header to remove
      outdated restrictions.  Changed example to reflect CSPICE
      version string.
      
   -CSPICE Version 1.0.0, 25-OCT-1997 (NJB)

      Based on SPICELIB Version 2.4.0, 31-JUL-1997 (WLT)
